This section explains the video interface between the Engine and Controller.
2-10-1. Overview of Video Interface
The Engine and Controller use a video interface to carry out the following functions. ·The transfer of image data. ·Mutual exchange (and confirmation) of data on the progress of the printing sequence. ·Data about the Engine is given to the Controller. ·Engine operation commands are sent.

2-10-2. Description of Signals
Signals /CPRDY Meaning of Signals This signal indicates that the Controller is ready for communication with the Engine following initialization of the CPU in the Controller after the main power is turned on. The signal becomes active when communication is enabled. This signal indicates that the Video Controller is currently transmitting the -CMD signal to the Mechanical Controller. This signal is the request by the Controller to the Engine, to start or continue printing. The signal becomes active when the Controller completes preparation of the image output. This is an 8 bit signal used by the Controller to control Engine operation. The type of operation is defined by the combination of 8 bits. This is an 8 bit signal used by the Engine to inform the Controller of the current status of the Engine. This signal is a serial synchronization clock for transmitting the -CMD and -STS signals. This signal is sent from the Controller to the Engine and initializes the Engine (resets the CPU). This signal indicates that the Engine is ready for communication with the Controller following initialization of the CPU in the Engine after the main power is turned on. The signal becomes active when communication is enabled. This signal tells the Controller whether or not printing is possible. The signal is inactive when there is a jam, the Fusing Roller is still warming up, etc. This signal indicates that the Engine is currently transmitting the -STS signal to the Controller. This is the horizontal (main scanning direction) synchronization signal which obtains the print start timing of each line during laser scanning. The signal is active during the period that the laser beam strikes the SOS sensor for each scan of the laser beam. This signal is an image data signal and is transmitted from the Controller to the Engine.

3-1. Paper Path
Paper can be fed into the printer either from the Multipurpose Tray (250 sheets) or the Manual Feed Port (1 sheet). The paper feed system can be extended to a 4-way system by installing the optional Second Paper Cassette Unit (500 sheets) and 3rd Paper Cassette Unit (500 sheets). In addition, duplex printing is possible when the Duplex Unit is installed. Paper fed by the Paper Take-up Roller is transported to the Image Transfer Roller, Fusing Roller, and Paper Exit Roller, then discharged onto the printer tray. When duplex printing, the printer pulls the paper into the Duplex Unit, and printing is performed on the back side of the paper.

3-2. Paper Take-up Section
3-2-1. Multipurpose Tray
Mechanism
- When the Paper Take-Up Solenoid (SL1) is energized, the drive of the Main Motor (M1) is transmitted to the Paper Take-Up Roller via the Paper Take-Up Clutch (oneway clutch) to turn the Paper Take-Up Roller one revolution. - At the same time, the Depressing Cam turns and lifts the Tray Lifting Plate, and the first (top) sheet of paper on the tray is fed into the printer. - The Fixed Separating Pad is used for the paper separation system. It prevents the second or later sheets of paper from being fed together with the top sheet. - As the Multipurpose Tray has no paper size detecting mechanism, it recognizes the paper size by the paper length, which is calculated from the time the paper passes over and activates the Paper Take-up Sensor (PS1). Therefore, sheets of paper having different widths are recognized as the same paper size if they have the same length.

Paper Empty Detection
The Paper Empty Sensor (PE1) on the upper section of the Multipurpose Tray determines whether paper is loaded in the tray. When paper is present, the actuator is lifted and the sensor is deactivated. When the tray has run out of paper, the actuator falls into the cutout in the tray and the sensor is activated.

3-2-2. Second and Third Paper Cassette Unit
Mechanism
- The Second and Third Paper Cassette Units have the same configuration. - As drive motors are not installed in these units, the drive for feeding and transporting paper (power from M1) is transmitted from the printer via the Drive Transmission Gear. - Although the feeding method is the same as the Multipurpose Tray in the printer, the corner separation system is applied as the paper separating method. - Paper is separated at the corner by the paper separation claw in the paper cassette and the strength of paper itself (corner separation system). One sheet of paper is fed for each paper feed cycle. - The Paper Take-up Solenoid (SL21) is controlled by the printer via PWB-A in the Second Paper Cassette Unit.
